There were a few issues but mostly the condo is quite good. Firstly the pick up was about 30 minutes late which was quite inconvenient. I understand there are traffic issues but that was a little annoying. The driver was very excellent and polite and helped me get into the building and showed me the basics. Once in the condo, I took a shower and was greeted by a giant cockroach running up the shower walls. After that it was a little hard to fall asleep easily. I know there are cockroaches all over Bangkok, but I have never seen one in a hotel or in a condo before. The other problem falling asleep was that the next-door neighbour had their music blasting until about 4:30 AM. The host told me they would contact the management the next day about the music and it did get a bit quieter.
Lastly, the swimming pool is totally useless. It is ice cold. The workout area seemed good. As people mentioned before the BTS and MTR are super close and convenient.
